I recently installed Visual Studio 2013 Ultimate. Now, as you know, there is this "n references" above all methods.
When I go to the CodeLens options, I can't disable this single feature, since the checkbox is grayed out.
So how can I disable it?
The References indicator is required to be on because it is the only one that knows how to do "placeholder" items (the one that says "- references"), and is guaranteed to show up everywhere that codelens appears.
If you could turn off references, then it is highly possible that codelens would reserve space for indicators, and yet no indicators would ever appear, so you would end up with blank lines on every method/class/property that aren't real blank lines, they're just reserved space for codesense elements that will never appear.
I'd suggest using the "send a frown" thing in visual studio and commenting about this if you want to turn just references off.
If you want to keep the CodeLens functionality but mostly get rid of the references, go to:
Options/Environment/Fonts and Colors
Show settings for: CodeLens
and change the settings to:
Font: Consolas
Font Size: 6
Indicator Text: White
Indicator Text (Disabled): White
Indicator Separator: White
Choosing Consolas reduces the line height beyond the default Calibri font, even at font size 6. There might even be a smaller font that you can use but I haven't found it.
If you have a dark background choose a matching dark color instead of White
where it is mentioned in the steps above, since the goal is to hide the CodeLense text.
